DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Drawings
The drawings are objected to because the empty boxes (e.g. 310, 315, 316, 903) in figures 3 and 9-11 should contain symbols or text indicating their functionality. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Figure 4-9 (see specification page 13; lines 8-10) should be designated by a legend such as --Prior Art-- because only that which is old is illustrated. See MPEP § 608.02(g). Corrected drawings in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. The replacement sheet(s) should be labeled “Replacement Sheet” in the page header (as per 37 CFR 1.84(c)) so as not to obstruct any portion of the drawing figures. If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Claim Objections
Claims 1 and 15 are objected to because of the following informalities: Claims 1 and 15, lines 13-14 recites “the first and second output switches”, which should be -- the third and fourth switches -- because this way is supported in the specification (see figures 9 and 10, part S3, 416 and S4).
Appropriate correction is required.
Claim 11 is objected to because of the following informalities: Claim 11, second line recites “to close the fifth and sixth switches”, which should be -- to open the fifth and sixth switches -- because this way is supported in the specification based on the type of fault (paragraph [0111]; Switch Fault Detection; Failure of either of the second or fourth switches S2, S4 may result in the DC power supply 401 being connected to the load 402, causing a rise in current above a predetermined magnitude threshold. This may be detected by either or both of the current sensors 901, 901, causing the controller 903 to turn the fifth and sixth switches SA1, SA2 off to protect the converter 900, 1000).
Appropriate correction is required.
Claim 12 is objected to because of the following informalities: Claim 12, lines 16-17 recites “the first and second output switches”, which should be -- the third and fourth switches -- because this way is supported in the specification (see figure 11, part S32, 4162 and S42).
Appropriate correction is required.
Claim 13 is objected to because of the following informalities: Claim 13, lines 1-2 recites “an electrical load”, which should be --the electrical load -- because this term was previously presented in the claim.
Appropriate correction is required.
Claim 17 is objected to because of the following informalities: Claim 17, lines 1-2 recites “closing the fifth and sixth switches”, which should be -- opening the fifth and sixth switches -- because this way is supported in the specification based on the type of fault (paragraph [0111]; Switch Fault Detection; Failure of either of the second or fourth switches S2, S4 may result in the DC power supply 401 being connected to the load 402, causing a rise in current above a predetermined magnitude threshold. This may be detected by either or both of the current sensors 901, 901, causing the controller 903 to turn the fifth and sixth switches SA1, SA2 off to protect the converter 900, 1000).
Appropriate correction is required.
Claim 18 is objected to because of the following informalities: Claim 18, line 7 recites “a DC-DC electric power converter”, which should be --the DC-DC electric power converter -- because this term was previously presented in the claim.
Appropriate correction is required.

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 2, 3, 9-11, 16 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Corti et al. (M. Corti et al. , “DC Networks Including Multiport DC/DC Converters: Fault Analysis”, IEEE Transactions on Industry, 09-01-2016.), hereinafter Corti, in view of Takeo et al.

It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to configure the fifth switch of Corti with the location of the fifth switch as taught by Takeo and obtain the fifth switch is connected between the second terminal of the first capacitor and the first switch, because it provides another efficient alternative to shutting off the circuit (column 6; lines 26-54). Additional, the applicant presented both location of the fifth switch (figure 9 and 10, parts SA1/SA2) as similar alternative for the DC-DC converter (Specification; paragraph [0106]).

It would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention to configure the first and second current sensors of Corti with the features of the first and second current sensors as taught by Takeo and obtain a first current sensor configured to measure current through the first output terminal and a second current sensor configured to measure current through the second output terminal, wherein the controller is configured to receive current readings from the first and second current sensors, because it provides more efficient and accurate current detection.

Regarding claim 11, Corti and Takeo teach everything claimed as applied above (see claim 9). Further, Corti discloses (figures 1-9) the controller (figures 1(b) and 2, part controller [not shown] that operate each switches S11/S12, S41/S42, fifth switch in lower side of PR1 and sixth switch in lower side of PR4) is configured to open [based on objection presented above] the fifth and sixth switches (figures 1(b), 2 and 3, parts fifth switch in lower side of PR1 and sixth switch in lower side of PR4; open) (page 3658; B. Solution B; third paragraph; this is not sufficient to clear the fault in terms of safety, and it is necessary to open the traditional circuit breaker) if the current readings from at least one of the first (figure 2, part upper current sensor of differential current sensor ∆IL4) or second current sensors (figure 2, part lower current sensor of differential current sensor ∆IL4) exceed a predetermined magnitude threshold (page 3659; V.
